The invention discloses a building material alternating concrete 3D printing device which comprises a plurality of independent printing units, each printing unit comprises a base, and a transverse moving module for driving a sliding seat to move on the base is arranged on the base; stand columns are arranged on the sliding seat, a cross beam is arranged between the stand columns, and a vertical moving module for driving the cross beam to move up and down is arranged on the stand columns; a printing moving module for driving the printing head to move along the cross beam is arranged on the cross beam; and the printing heads of the plurality of printing units perform alternate printing. The invention further discloses a building material alternating concrete 3D printing method. According to the concrete 3D printing device and method adopting the alternate building materials, the problems that existing concrete 3D printing is high in cost and poor in performance can be solved, and rapid printing of a multi-mater
